Enterprise Application Modernization Companies Offer Solutions for Legacy Systems

Remain Software, an IBM Business Partner founded over 25 years ago and headquartered in the Netherlands with a U.S. office in Norfolk, Virginia, provides Application Lifecycle Management (ALM) and DevOps tools for IBM i, Windows, and Unix/Linux environments. Its flagship product, TD/OMS, delivers graphical impact analysis, one‑click rollback, source comparison, automated deployment, workflow automation, and audit‑ready reporting for compliance standards such as SOX, while integrating with platforms like Jenkins, Git, JIRA and ServiceNow.

Other vendors highlighted for enterprise‑scale modernization include Corsac Technologies, which uses AI to map complex codebases, uncover hidden dependencies, and document business logic before any rewrite, and Reliqsy, which applies AI to analyze .NET, Java and monolithic applications to surface technical debt. Both aim to reduce risk and scope creep in projects that must modernize legacy applications tightly coupled to ERP, CRM and other internal systems.
